This comprehensive guide breaks down the bathroom renovation cost Sydney homeowners can expect. We will explore demolition, tiling, plumbing fixtures, and labour rates so you can budget with confidence.

Average Bathroom Renovation Cost in Sydney

The average cost to redo a bathroom depends heavily on the room's size, your choice of materials, and whether you are changing the underlying plumbing structure.

To help you establish a baseline, here is a quick look at the average bathroom renovation cost Sydney residents typically face:

• Budget / Cosmetic Update: $5,000 – $10,000. Involves keeping the layout the same, repainting, updating tapware, and fitting a new vanity or toilet.


• Standard Mid-Range Renovation: $15,000 – $25,000. Includes full waterproofing, new mid-range tiles, a new shower screen, freestanding bath, and relocating minor plumbing.


• Premium / Luxury Renovation: $30,000 – $50,000+. Features structural changes, high-end stone tiles, custom cabinetry, smart toilets, and underfloor heating.

Estimated Cost to Renovate a Bathroom (Breakdown)

When calculating the estimated cost to renovate a bathroom, it helps to see where your money goes. As a general rule of thumb, bathroom renovation costs are split between materials (40%) and labour (60%).

Here is a quick percentage breakdown of a standard cost to renovate bathroom projects:

• Labour (Plumbers, Tilers, Electricians): 40% - 50%


• Tiles & Waterproofing: 15% - 20%


• Plumbing Fixtures (Toilet, Bath, Shower): 15% - 20%


• Cabinetry & Vanities: 10% - 15%


• Lighting & Ventilation: 5%

Bathroom Demolition Cost

Before you build, you must clear the space. The average bathroom demolition cost in Sydney ranges from $500 to $2,500. This depends on the size of the room and ease of access.

Demolition is more than just smashing tiles. It requires the safe removal of existing fixtures, careful stripping of old waterproofing, and waste disposal (skip bins).

If your home was built before the 1990s, you may also encounter asbestos. Asbestos removal must be handled by licensed professionals and will increase your demolition costs by $1,000 to $3,000.

Bathroom Tile Renovation Cost

Tiles define the look and feel of your space. Your bathroom tile renovation cost generally accounts for a significant portion of your materials budget, ranging from $1,000 to $5,000+.

Basic ceramic tiles start at around $30 per square metre, making them great for budget updates. Mid-range porcelain tiles usually cost between $50 and $80 per square metre.

If you prefer high-end natural stone or custom artisan tiles, expect to pay $100 to $200+ per square metre. Remember, intricate tile patterns (like herringbone) will also increase the tiler's labour fee.

Toilet Renovation Cost

Upgrading your toilet is a highly practical investment. The average toilet renovation cost spans from $150 to well over $1,500, depending on the model and plumbing requirements.

• Basic back-to-wall toilet: $150 – $350


• Mid-range rimless toilet: $400 – $800


• High-end in-wall hidden cistern: $1,000 – $2,000+

Keep in mind that installing an in-wall cistern costs more in plumbing and carpentry labour, as the wall cavity needs to be modified to house the water tank.

Bathroom Redesign Cost & Fixtures

A full bathroom redesign cost involves plotting new layouts and upgrading major fixtures like vanities, sinks, and tapware. Getting the design right ensures your space is functional and visually striking.

For a basic pre-made vanity, expect to pay between $400 and $800. Custom-built, wall-hung timber vanities with stone benchtops can easily push the price to $2,500 or more.

Tapware and sinks also vary. Standard chrome mixers cost around $100 each, while designer matte black or brushed brass tapware can cost $300 to $800 per piece.

Tub and Shower Costs

Tubs and showers are the focal points of any bathroom renovation. A standard acrylic built-in bathtub will cost between $300 and $700. If you want a statement freestanding tub, budget between $1,000 and $3,000.

Showers have varying price points based on the screen and showerhead. A standard framed glass screen costs roughly $500, whereas a custom frameless glass enclosure ranges from $1,200 to $2,500.

Upgrading to a multi-function rainfall showerhead adds $200 to $600 to your overall plumbing fixture budget.

Apartment Bathroom Renovation Considerations

Renovating a bathroom in a Sydney apartment involves strict strata by-laws and body corporate regulations that can influence your overall costs.

You must submit a formal renovation plan for approval before commencing work. Strata often require you to use acoustic underlay and specific waterproofing membranes to prevent leaks to units below.

Logistics also play a role in pricing. Moving materials up service elevators, restricted working hours, and difficult waste removal can add 10% to 20% to your contractor's quote.

Small Bathroom Remodel Cost

You might assume a smaller footprint means a massive price drop. However, the average small bathroom (around 4-5 sqm) still requires all the same trades as a large one.

A standard small cost to renovate bathroom project in Sydney ranges from $10,000 to $15,000.

To maximize space, homeowners often use in-wall toilets and custom cabinetry, which carry higher installation fees. Therefore, focus on smart layouts and mid-range finishes to keep costs down in compact spaces.

Premium & Luxury Bathroom Costs

If you are building your dream spa-like retreat, a premium bathroom remodel will typically exceed $30,000.

Luxury costs are driven by high-end materials like marble slabs, smart toilets, double walk-in showers, and heated flooring.

Additionally, complex designs require top-tier craftsmanship. Custom lighting plans, niche shelving, and seamless floor-to-ceiling tiling demand experienced, specialist tradespeople, raising both material and labour expenses.

Labour Costs for a Bathroom Renovation in Sydney

Labour is a major factor in bathroom renovation costs. Due to high demand and living costs in Sydney, licensed tradespeople charge competitive rates.

• Plumbers: $80 – $120 per hour. They handle pipe relocation, drainage, and fixture installations.


• Tilers: $60 – $90 per hour (or $50 – $120 per sqm). Crucial for a flawless, level finish.


• Electricians: $80 – $110 per hour. Responsible for safe lighting, exhaust fans, and heated towel rails.


• Waterproofers: $50 – $80 per hour. Waterproofing is a legal requirement in Australia and must be certified.

Additional Renovation Costs

Depending on the scope of your project, you may need to factor in peripheral expenses. If you are moving walls or altering the property's structure, you will need to hire an architect or structural engineer, which can cost $2,000+.

Professional painters are required for wet-area ceilings and trims, charging roughly $40 to $60 per hour.

Finally, don't forget council permits. If your renovation alters the home's exterior (like adding a new window) or requires major sewer work, permit fees will add to your total budget.

How to Save on Bathroom Renovation Costs

Bathroom renovations are expensive, but smart planning can help you achieve a high-end look without blowing your budget.

• Keep the existing layout: Moving plumbing lines for toilets and drains is the fastest way to increase costs. Keeping fixtures in their original spots saves thousands in plumbing labour.


• Choose standard-size fixtures: Custom vanities and custom glass shower screens are pricey. Opt for off-the-shelf, standard-size products.


• Tile strategically: Instead of floor-to-ceiling tiles, tile only the wet areas (shower and bath) and use specialized wet-area paint for the rest of the walls.


• Hire a project manager: While it sounds counterintuitive, utilizing professional bathroom renovators in Sydney can save you money. They get trade discounts on materials and manage trades efficiently to prevent costly delays.
